Microsoft's new homegrown search engine on MSN is the subject of a $200 million marketing campaign designed to wrest loyal users away from rivals Google and Yahoo!, using TV spots by McCann-Erickson, San Francisco, and a viral marketing campaign by 42 Entertainment. The MSN search ads will air as local spots during Super Bowl XXXIX, as well as during the NCAA basketball tournament and the Grammy awards.
